RE: Vacuum form a clear canopy!
diony:
Sorry I didn't read your first post closely enough. "...post my experiences in trying to form the perfect canopy!..."
The Perma stone is less than $10 a can to try, but looking at your finished canopy, not as good as your method.
I like it because it is a lot harder than plaster, ready to use the next day without coating and produces a not-bad result.
The missus is around so I have to wait awhile to use the oven to try to form a new canopy to take a picture of.
